Abstract

The research is a classroom action researched aiming to improved creative thinking skilled and biology learning result by implemented GGE (Group to Group Exchange) learning model with Sequence Chains on students of class X MIPA 4 SMAN 1 Gambiran Banyuwangi academic year 2017/2018 which is done two cycles. Stages cycles includes: planning, action, observation, and reflection. The result of the research of creative thinking skill on pre-cycle is 32,02 increased 43,82 to be 75,85. In learning result, pre cycle cognitive learning comprehensiveness is 43,75% increased 37,5% to be 81,75%, while for effective achievement in the pre-cycle is 36,71 increased 41,58 to be 78,32. Based on the above explanation, it can be concluded that the implementation of GGE (Group to Group Exchange) with Sequence Chains can improve creative thinking skill and learning result of students class X MIPA 4 SMAN 1 Gambiran Banyuwangi academic year 2017/2018.

Abstract

Infectious diseases caused by animal vectors are currently still a health problem in the world even in Indonesia, especially the Aedes aegypti mosquito which is the vector for the spread of dengue fever. Chemical control is still a priority for the community, such as the use of abate. Continuous use of abate can cause resistance to the Aedes aegypti mosquito to the next generation and pollute water conditions. One of the control solutions can be done with natural insecticides such as amethyst fruit (Datura metel L.). The purpose of making purified extracts is to remove unnecessary impurities and get a larger content of active compounds and increase the concentration of active compounds. The concentration of amethyst extract (Datura metel L.) used was a concentration of 100 ppm, 500 ppm, 1000 ppm, 1500 ppm, 1gr abate as a positive control and aquades as a negative control. The amount of Lethal Concentration-50 (LC50) purified extract of amethyst fruit (Datura metel L.) with n-hexane was 494.987 ppm. The active compound content of amethyst fruit (Datura metel L.) in the n-hexane fraction after a phytochemical screening test was carried out was positive for alkaloids, steroids, terpenoids and tannins. The toxicity of the purified extract with n-hexane of amethyst (Datura metel L.) against Aedes aegypti mosquito larvae within 24 hours is considered toxic because it has an LC50 value of less than 1000 ppm.

Abstract

Morinda citrifolia L. is known commercially as mengkudu, grows widely throughout in Indonesia and is one of the most significant sources of traditional medicines. In fact, mengkudu contains a very important alkaloids, xeronine. This alkaloid helps in the normalization of abnormally functioning cells. This research aims is to knowing the influence of Morinda citrifolia L. fruit to the number of neutrophil cell in male mice scratch wound. There was 6 group as a treatment group, in which every group contain 4 mice. Every group had different time in neutrophil cell observation, it was 12, 24, 36, 48, 60 and 72 hour/ observation. The result showed that the number of neutrophil cell tend to decrease. And based on LSD test the number of neutrophil cell different signicantly in 48 hour of observation.

Abstract

Granules extract of clime fruit (Citrus aurantifolia L.) is a biolarvasida in eradicating Aedes aegypti mosquito larvae L. Granules extract of lime fruit (Citrus aurantifolia L.) can kill mosquito larvae because its content of limonoida, tannin, flavonoid, and volatile oil. The compound is lethal to the larvae which will enter the body of the larvae of the Aedes aegypti L. mosquito which disrupts the systems in its body. The purpose of this article is to determine the safety of lime fruit (Citrus aurantifolia L.) extract granules on non-target animals, namely tadpoles. Tadpole has the same habitat with mosquito larvae so it is done safety test of citrus fruit extract granule (Citrus aurantifolia L.). Tadpole is a larval phase in Amphibi that continues to experience morphological development in water. The initial phase of tadpoles growth is a phase of adaptation to its habitat. Individuals who can not adapt well will experience a faster death. The research method used is laboratory experimental. The analysis used is ANOVA. The independent variables in this study were the variety of granules extract concentration of citrus fruit (Citrus aurantifolia L.). Tadpole mortality became the dependent variable in this study. Tadpole mortality is characterized by tadpoles collapsing at the time of administration of granules. The results showed that the lime extract granules (Citrus aurantifolia L.) proved safe.

Abstract

The study was aimd to develop a valid, practical, and effective E-Module based on Adobe flash. This research was development research. Data collection techniques used questionnaire analysis, pre-test/post-test, student response questionnaire, and validation from the experts. The design of the research is development E-module based on Adobe Flash media using a 4-D model (Define, Design, Develop, Disseminate) that developed by Thiagarajan (1974). The results indicated that the level of validity of developed E-Module based on Adobe Flash was 82.54%, 83.89% , 79.58%, based on experts of subject, media and media development respectively, while developed media validity according to teacher as user was 88,93%, practical was 91,11%, effective was 0,72.

Abstract

The study entitled the effect of STEM (Science, Technology, Engineering, and Mathematics) based textbooks in biotechnology learning material on the critical thinking skills and learning results of senior high school students in the industrial agriculture area. The purpose of this study was to determine the effect of STEM-based textbooks on the subject of biotechnology on critical thinking skills and student learning outcomes in industrial agriculture areas. This type of research is quasi-experimental research (quasi experiment). The sampling technique was carried out through the normality test and ANOVA homogeneity test using the end of semester exam scores for biology subject then the determination of the sample was carried out randomly (random sampling). The research samples were class XII MIPA 2 as the experimental class and XII MIPA 4 as the control class. The place of this research is at SMAN 3 Jember. Data analysis used the covariance analysis test (Anacova) and Independent Sample T-Test for data that met the parametric test requirements, namely normal and homogeneous. The significance value obtained was <0.05 so it can be concluded that there is an influence of STEM (Science, Technology, Engineering, and Mathematics) based textbooks on the subject of biotechnology on critical thinking skills and learning outcomes.
